Thanks guys for the feed-back...since it's a huge model with a lot of greeblies (they had to dress that model on all sides, since it was turning all the time ) I'm slowly finishing the first cone (details and everything) and then, I'll build the second one.
When that's done, I'll do the tube connecting the 2 modules...and when everything is said and done, I'll ship it to England, find the two gas towers and throw the model in a grass field...kidding of course

Thanks Starrigger! I just added the "ladders" on the module and I'm starting to put the "air units" on the spokes (8 per spoke, 8 spokes, 8X8=64 air units to affix) ; as you can see, that station keeps on giving!
